the number of years that brad has been on the soccer team is 2 less than 5 times the number of years that Scott has.in total,the
Alexeev081 [22]
Assume the following:

Brad has been in the soccer team for b years.

Scot has been in the soccer team for s years.


"The number of years that brad has been on the soccer team is 2 less than 5 times the number of years that Scott has"

means: b=5s-2


"in total,the boys have been on the soccer team for 10 years."

means: b+s=10


so we have the equations:

i) 
b=5s-2

ii) 
b+s=10


substitute b in ii) with 5s-2, as they are equal, from i

(5s-2)+s=10

5s-2+s=10

6s=12

s=2, 


then , from b+s=10, b=8


Answer: Brad has been in the team for 8 years.

Felix scored 52 and 64 on his first two test in Sociology 212. What must he get on the third test to get an average of the three
Pie

Answer:

Felix's third test score must be greater than 94

Step-by-step explanation:

Felix scores on Sociology 212 tests:

1st test - 52

2nd test - 64

3rd test - x

Find the average of Felix's scores:

\text{Average}=\dfrac{\text{The sum of all scores}}{\text{The total number of scores}}\\ \\\text{Average}=\dfrac{52+64+x}{3}

An average of the three test must be above 70, this means

\text{Average}>70\\ \\\dfrac{52+64+x}{3}>70

Solve this inequality. First, multiply it by 3:

52+64+x>210\\ \\x>210-52-64\\ \\x>94

You invest $6.500 into a mutual fund that is expected to earn 6% per year. How long will it take the fund to earn $13,000?
Vesna [10]
Y= $6.500(1.06)^x

13000= $6.500(1.06)^x
2000=(1.06)^x

log 2000 = x log 1.06 
x= log 2000/ log 1.06
